RECUPEBATOR.

Application led Februaly 9, 1923. Serial No. 618,035.

To all whom t may concern:

Be it known that I, ROBERT GOOD, a citizenof the United States, and a resident lof VVaShington, ,in y the .county I of Washington and Stateof Pennsylvania, have invented new and useful Improvements in Recuperators, of which the following is a full, clear, and exact description.

One of the serious disadvanta-ges Of previously known reeuperator constructions has been the leakage between the air f lues and the waste gas passages; and One of the objects of the-present invention is to `provide a construction which will prevent such leakage. g

Another object of thelnventlon 1s to provide a recuperator which posseses a very high degree of durability, and 1n which the construction issuch that the tiles, brick, etc., may be removed and renewed,l when necessary, with comparative ease.

Other objects and vadvantagesaof the invention will be apparent to those Skilled in the art from the following detailed description, when taken in connect-ion with the accompanying drawings, in which:

Figure 1 is a longitudinal, vertical, sectional view of the recu erator.

Figure 2 is a vertica Sectional view taken 'on line 2-2 of Figure 1; and

Figure 3 is a detail sectional view, on an enlarged scale, and clearly showing the relative arrangement of the tile and brick, and the joint therebetween. A

Referring to the drawings more in detail, numeral 1 indicates the usual recuperator walls, having the ordinary air intake port 2 provided adjacent the bottom thereof. A plurality of I beams 3 are mounted in the recuperator walls above the air intake port, and on these I beams rest the base blocks 4. These base blocks Support the tiles forming the air lues, as will appear hereinafter.

It will be understood,`of course, that the base for supporting the tiles may be of any desired construction, and thatithe specic construction thereof, as illustrated and described herein, is merely the preferred form.

The recuperator includes a plurality of vertical lues for the passa-ge of the combustion air to be preheated, said lues being indicated by the numeral 5; vand a series of horizontal passages for the waste gases, said horizontal passages being indicated by numeral 6.

The vertical l'ues are formed of a series of tiles, all of which are identical in construction. The tiles are indicated by numera17, and they are nothing more' than conventional tiles having the usual bell mouth at one end, and being plain\at the other end; so that the plain end of one tile' tits'into the bell mouth of the tile below it.

-The construction is Obvious from an inspection of the drawings, the plain end of' one `tile is received withint-he flange 8 of the next lower tile, and the plain end rests on the shoulder 9 of this lower tile. The tile illustrated herein are formed with a single passage therethrough; but tiles having a .plurality of passages are well known, and,

of course, the present invention conteniplates the use of such tiles, if preferred. The tiles are shown herein as rectangular in cross section, though any other form may be employed, if preferred. `Further, the tiles #forming the vertical flues are shown .as having the bell mouth at the top, but it is Obvious that the arrangement could be reversed, so that the bell mouth 'would be at the lower end of each tile; in `which case the bell mouth of the lower end of a tile would tit over the upper plain end of the next7 lower tile.

The horizontal passages for the waste gases are formed by a plurality of horizontal battles, causing the gases to follow a circuitous course, as in the ordinary recuperator constructions; but the present invention discloses a novel means for forming and supporting the bales'or diaphragms. The bricks forming these baies are indicated by numeral 10, and they are designed tol fit between the vertical lues and be supported by the flanges or shoulders 8 of the vertical tiles, as clearly shown in the drawings.

The simplicity of the construction is apparent from the foregoing description. ,'lhe vertical lues are formed of a series of conventional bell mouth tiles, and the horizontal passages for thewaste gases are formed of battles or diaphragms constructed of plates, bricks, or the like, supported on the numeral 11.

tions of the vertical lues, but they also act as a support for the bricks forming the horizontal battles or diaphragms.

It is highly desirable that mortar or similar jointing material be employed in the construction of the Vertical flues and horizontal passages, and the use of jointing material is illustrated in Figure 3, being referred to by It will be obvious `from an inspection of Figure 3 that the construction and relative arrangement of the parts are such that the jointing material may be easily and effectively applied.

It will be apparent that in a recuperator constructed in the above described manner there will be no possibility for any leakage to occurbetween the air 'and Waste gas passages in the normal operation of the recuperator, and nothing short of the breaking of one of the tiles will cause the mixing of the air and Waste gases.

The courses of the air and waste ases through the recuperator are clearly lndicated in the drawings; the course of the air being indicated by single headed arrows, and the course of the Waste gases being indicated by double headed arrows. The waste gases are shown as traveling back and forth through a single passa e; but it will be understood, of course, t at the arrangement may be varied so that the gases will trave-l in one direction through two or more flues,

and then return through a similar number of passages located below.

It is to be noted that the vertical lues constitute a series of independent chimneys, each presenting a free and unobstructed passage for the air to be heated.

What I claim as new and desire to secure by Letters Patent is:

l. In arecuperator construction, a plurality of vertical lues arranged in horizontal alignment,`a plurality of horizontal baffles forming passages for the wastev gases through the recuperator, said vertical lues formed of conventional bell-mouth tiles arranged end to end, each of said horizontal baffles arranged in a continuous line from sidev to side of the recuperator and supported on the bell-mouth flanges.

. 2. In a recuperator construction, a plurality of vertical lues arranged in horizontal alignment, said vertical flues formed of conventional bell-mouth tiles arranged end to end, the vertical llues arranged in abutting relation to form a continuous wall, the walls thus formed being spacedto form passages, a plurality of horizontal baies arranged in said passages, `said horizontal bailes arranged in a continuous line from side to side of the recuperator and supported on the bell-mouth langes.
